Please contact me if you find any error in one of my publications. I gather them on this page.
Matrix-wise L0
In the paper Matrix-wise L0-constrained Sparse Nonnegative Least Squares, equation (8) is printed as
|| vec( B ) - (A \kron I) x ||_2
but in reality it should be
|| vec( B ) - (I \kron A) x ||_2
.
Thanks to Alexander Viguerie (CDC, USA) for spotting this typo. The same typo is present in my PhD thesis, page 80, equation (4.2).
